With Standard Gear Pumps between your extruder and die you can directly dial in gauge control, eliminating extruder surge and screw beat at the die. This type gear pump also called gear melt pump.

Extrusion Line Synchronization Made Easy. With a Batte gear pump between your extruder and die you can directly dial in gauge control, eliminating extruder surge and screw beat at the die. Extruder screws efficiently melt, mix and convey polymer, but are not as efficient at providing a consistent pressure and volume to the die. A gear pump, while not a mixing or melting device, is extremely efficient at building pressure and metering the polymer output.

The Batte Gear Pump is a positive displacement device which provides a linear output over a wide range of operating conditions. A closed-loop drive control varies extruder screw speed to assure an adequate amount of polymer to the pump regardless of inlet pressure variations due to extruder surge and screw beat. Precise construction makes Batte Gear Pumps extremely accurate volumetric metering devices. Each gear tooth “bucket” carries a precise, repeatable amount of polymer melt to the output side of the pump.
